Glass Ball as Bullet Solubility System: Styrene with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Styrene; C8H8; [100-42-5]  NIST Chemistry WebBook for detail
Original Measurements:
   Frilette, V.J.; Hohenstein, W.P., J. Polym. Sci. 1948, 3, 22-31.

 Variables:
   Temperature = 25 °C

 Prepared By:
   A. Maczynski and Z. Maczynska

 Experimental Remarks:
   The solubility of styrene in water at 25°C was reported to be 0.022 g(1)/100 g sln.

The corresponding mole fraction, x1, value calculated by the compilers is 3.8 × 10–5.

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   The saturated solutions of (1) in (2) were prepared in two different ways. In the first method, conjugated solutions were prepared by shaking together excess (1) with (2) and allowing the layers to separate; the aqueous layer was then analyzed for (1). To avoid the possibility of contaminating the aqueous phase by small suspended droplets a second method was utilized; a cellophone sack, filled with (2) was completely submerged in a beaker containing (2); a layer of (1) was then floated on top of (2) in the beaker. After 48 hr at 25°C, the sack was retrieved and the contents carefully removed and analyzed.

The method of analysis was not described.
